How can I configure Json serialization and deserializtion

[Sachin Mittal]

Hello,

In our vert.x web application we are processing JSON body post request.

Hence we deserialize it into POJO, do certain transformations and again serialize into JSON.

During this step we would like to control the process like

1. Ignore unknown fields

2. Do not serialize null fields

3. Do not serialize doubles in scientific notation.

I understand that under the hood, vert.x uses Jackson, however we don't have access to ObjectMapper of Jackson directly.

Is there a way we can configure these (and possibly others what Jackson allows), during both deserialization and serialization process.

Thanks

Sachin

    ObjectMapper mapper = io.vertx.core.json.jackson.DatabindCodec.mapper();
    
    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    
    mapper.registerModule(new JavaTimeModule());
